Marine sensors

Flexible and reliable sensors for Marine applications.

Sensors for electronically controlled safety functions are the eyes, ears and the antenna of a modern-day high-tech vehicle. Nothing escapes them – neither the smallest temperature deviation inside cooling systems, nor the monitoring of engine and gear oil temperature. Intelligent safety systems are inconceivable without them.

Nav sensor

The multifunctional AcquaLink Nav Sensor is the gem of all sensors. The inertial sensor complements the inbuilt satellite receiver module (GPS, Bei Dou, Glonass, Galileo) to provide accurate readings of the speed of travel as well as the pitch & roll (up and down) and YAW (sideways) motion of the boat.

Compass readings can be displayed electronically thanks to the fluxgate, which also facilitate course corrections in electronic autopilots. The barometer and air temperature sensors are early indicators of forthcoming weather conditions.

Wind sensor

The wind vane turns in the direction of the wind and steers the wind direction gauge. The rotor records the relative wind speed which in turn is diplayed on the wind speed gauge.

Sumlog® Transducer

The Sumlog® Transducer is required to measure boat speed through water. The Sumlog® includes two paddle wheels which can be exchanged to match the speed range of the boat, thereby supporting speeds from 0 to 12 or up to 50 knots respective of the installed paddle wheel.

The Nav Box supports up to two Sumlogs® which can be directly connected to the dedicated Sumlog® ports using a 4 pin M12 connector extension cable.

Depth sensor

This depth sensor is a low-profile, retractable, thru-hull sensor that computes accurate depth and temperature data and sends it to any NMEA 0183 or NMEA 2000® display. It operates at a frequency of 235 kHz. The broadband ceramic delivers depth readings to 183 m (600’), as well as accurate shallow-water readings in as little as 500 mm (1.6’).

The signal from the depth transducer is processed right inside the sensor itself. All that is needed to receive depth and temperature data is a single cable into a compatible device or display. Because the ceramic is tilted inside the housing, the transducer beam is oriented straight down, resulting in strong bottom echo returns and accurate depth readings. The retractable housing with a self-closing valve reduces water flow into the vessel when the transducer is removed for cleaning.

Sensors for electronically controlled safety functions are the eyes, ears and the antenna of a modern-day high-tech vehicle. Nothing escapes them – neither the smallest temperature deviations inside cooling systems, nor the monitoring of engine and gear oil temperature. Intelligent safety systems are inconceivable without them.

The temperature sensor is based on NTC-Technology (Negative Temperature Coefficient). It is a semi-conductor which changes the resistance value according to temperature deviation. This resistance value as an output value is much more an indication of a media’smedium temperature.
